MECHANISM FOR INDICATING- TIMELY ACTION IN LOOMS.

Specification of Letters Patent.

Patented Dec. 22, 1908.

Application filed February 26, 1906. Serial No. 303,039.

To all whom it may concern:

Be it known that I, WILLARD W. BARDS- LEY, a citizen of the UnitedStates, residing at Providence, in the State of Rhode Island, haveinvented a new and useful Improvement in Mechanisms for IndicatingTimely Action in Looms, of which the following is a specification.

This invention relates to a mechanism which serves to indicate theproper time for the performance of a specific movement in some portionof the mechanism of a loom, as for instance, the time for operating theshuttle-box motion. And it consists in the combination of a plurality ofrotary annular multiplying elements of different diametrical dimensionsprovided with means for positive engagement with a driver, and withperipheral means, which when arranged in proper line with one anotherserve to cause the movement of an arm which is in indicative connectionwith the loom mechanism wherein a timely operative action is required.

In the accompanying drawings, Figure 1 represents a plan view of anindicating mechanism embodying my improvement. Fig. 2 represents a sideelevation of the same. Fig. 3 represents an end elevation. Fig. 4represents the opposite end elevation. Fig. 5 represents an enlargedsection taken in the line 5 5 of Fig. 2. Fig. 6 represents an outer endview of the operating gear for the multiplying elements, and an outerside view of the connected stop wheel and ratchet wheel. Fig. 7represents a side view of the operating gear, and an edge view of thestop wheel and the ratchet wheel. Fig.8 represents a side view of one ofthe multiplying elements provided with a single peripheral notch. Fig. 9represents an edge view of the same. Fig. 10 represents a side view ofone of the multiplying elements provided with a plurality of peripheralnotches. Fig. 11 represents a vertical section taken in the line 11 11of Fig. 2. Fig. 12 represents a vertical section taken in the line 12 12of Fig. 2. Fig. 13 represents an enlarged side view showing amodification in which the multilying elements are formed of unequalendless flexible chains. Fig. 14 represents a side view of the u perportion of one of the said endless fiexib e chains. Fig. 15 representsan edge view of the same. Fig. 16 represents the side view of thesprocket wheels for the said chains, and the outer side view of theconnected ratchet wheel, the stop wheel being removed. Fig. 17 reresents an edge view of the sprocket whee s and of the stop wheel andratchet wheel. Fig. 18 re resents a plan view showing a modification inwhich the indicating elements are located up on sep arate shafts insteadof being placed side by side. Fig. 19 represents a side elevation of thesame. Fig. 20 represents a side view of the opposite indicating arms ofthe mechanism. Fig. 21 represents the top view of an indicating armadapted for employment in connection with rotary indicating elementsprovided with peripheral elevations, instead of the depressions. Fig. 22represents a section taken in the line 22 22 of Fig. 21, showing theindicating arm in its raised position. Fig. 23 represents the samesection showing the indicating arm in its lowest position. Fig. 24 reresents a side view of one of the rotary mu tiplying elements having asingle peripheral projection, the said multiplying element being shownon a diminished scale. Fig. 25 represents a side view of a multiplyingelement provided with three peripheral projections. Fig. 26 representsan edge view of the same.

In the drawing, A represents the frame of the machine, and B a fixedhorizontal spindle which is held from rotation by means of the setscrews a 60. Upon the outer end of the rock-shaft C is secured thereciprocating arm D, from which suitable connection is to be made withthe motive power. And to the opposite end of the said rock-shaft C issecured the upright arm E, to the upper end of which are pivoted thegravitating ratchet pawls F and G, the pawl F operating upon the teethof the ratchet wheel H, and the pawl G upon the teeth of the ratchetwheel I. The fixed spindle J is secured to the upper end of the standardK of the frame of the machine, by means of the set screw b, and upon thesaid fixed spindle J is loosely pivoted the indicating arm L, which armis in tegrally connected with the ratchet guard M. And also upon thesaid fixed spindle J is loosely pivoted the indicating arm N, which isintegrally connected with the ratchet guard O.

The ratchet wheel I is fixedly secured to the hub of the gear wheel P,and at the outer side of the ratchet wheel I is secured the notchedstop-wheel Q, the notches c c of the said stop-wheel being engaged bythe roller R, which is located at the upper end of the bell-crank leverS, the said roller being held in contact with the peri hery of the saidstop-wheel, by means of t e spiral spring d.

The gear wheel P is arranged to turn loosely upon the fixed spindle B,being held thereon by means of the adjustable collar 6, and upon thesaid gear wheel and engaging with its teeth are placed a series ofmultiplying elements consisting of the disks T T T, having one or morenotches f in their peripheries, whereby the radial distance of theperipheral surface will be varied and rovided with the internal gearteeth g, wiich enga c with the external teeth h of the gear whee P. Theannular multiplying elements T T T are provided with an unequal numberof teeth whereby the times of their revolution will be varied,respectively, whereby a comparatively great number of revolutions nectedratchet of the gear wheel P will be required in order that themultiplying elements T T T shall have arrived at such a number ofcomplete revolutions that the peripheral notches f of the severalmultiplying elements will lie under the laterally elongated bearing headof the indicating arm L, thus causing the said bearing head to sink intothe said notches. And upon the sinking of the head 1' of the arm L, theratchet guard M, which is integr'ally connected with the said arm, willbe depressed so as to allow the ratchet pawl F to engage with the teethof the ratchet wheel H, and thus cause the rotation of the pattern chainsprocket wheel X, which turns loosely upon the fixed spindle B, and towhich the said ratchet wheel H is connected. At the side of the ratchetwheel H upon the hub of the pattern chain sprocket wheel X is securedthe stop wheel U, the notches 7c 7c of which are engaged by the roller Rlocated at the upper end of the bell-crank lever S the said roller beingheld in contact with the periphery of the said stop-wheel, by means of te spiral spring (1 Now upon the rotation of the pattern chain sprocketwheel X, such motion will at the proper time cause one of the chainelements V, having a riser, to be brought under the elongated shoe n ofthe said indicating arm N, thus causing the elevation of the ratchetguard O, and the consequent elevation of the ratchet-pawl G, out ofengagement with the teeth of the ratchet wheel I, and thus stopping theaction of the multiplying mechanism; and as long as each succeedingelement V of the pattern chain is provided with a riser adapted forengagement with the elongated shoe n of the arm N, the multiplyingmechanism will remain ino erative, but as soon as a chain element witout a riser arrives under the shoe if, then the arm N and its integrallyconuard 0 will be depressed, thus throwing 516 multiplying mechanisminto, operation, and the primary action of the pawl G upon the ratchetwheel I will serve to cause the rising of the arm L from the peripheralnotches f, thus causing the simultaneous elevation of the ratchet guardM, and consequent disengagement of the ratchet pawl F from the teeth ofthe ratchet wheel H, and the consequent stopping of the action of thesprocket wheel which carries the pattern chain.

A modification of my invention is shown in Fig. 13, in which themultiplying elements are constructed of the endless flexible chains W W,instead of the disks T, one of the chains being made comparatively thinto allow for the depression of the indicating arm L, at the proper time,which time is determined by the occurrence of the de )ressed chain links0 of the several chains W, in the established line for the action of theindicating arm L. The multiplying elements W W are carried by thesprocket wheels 1) 1), upon the hub of the ratchet wheel I, and the stopwheel Q, and being of unequal dimensions the time of the requiredcoincidence of the indicating elements of the several chains will begreatly extended, and by lengthening or shortening the chains may beregulated as desired.

Another modification of my invention is shown in Figs. 18 and 19 inwhich the multiplying elements T T are placed upon the separate spindlesB and B and the indicating arms L L connected with each other as shownin Fig. 20, the inner end a of the indicating arm L extending under theinner arm 6 of the said arm L whereby the movement of the indicating armL and .ratchet guard 0 cannot be effected until the indicating arm L haspassed into the notch f of the multiplying element T The ratchet wheelsI and I are operated alternately from the arm E by means of the pawls Gand G and the ratchet guards O O are operatively connected with eachother for simultaneous movement.

, Another modification is shown in Figs. 21,

22 and 23, in which the peripheries of the multiplying elements T T areprovided with the projections f instead of the depressions f, or J, andin this case the indicating arm L is provided with the pivoted catches gg g, which are adapted for normal engagement with the fixed shelf 1',but when the said levers are simultaneously engaged by the projectionsof the several multiplying members, the indicating arm L willfall asshown in Fig. 23, and thus insure the desired movement in the connectedmechanism.
